[0015] The following specifically describes the specific embodiments of the present utility model with reference to the drawings.

[0016] Embodiment:

[0017] As shown in the accompanying drawings, a specific embodiment of a horizontal self-cleaning filter of the present utility model is as Figure 1, which mainly includes a filter housing 1. The interior of the filter housing 1 is partitioned into a water inlet chamber 1a, a filtration chamber 1b, and a cleaning chamber 1c. Among them, a water inlet 2 is connected to the water inlet chamber 1a. A filter cartridge 3 is provided in the filtration chamber 1b. The bottom end of the filter cartridge 3 is communicated with the water inlet chamber 1a, and the top end is hermetically connected to the cleaning chamber 1c. A water outlet 4 is connected to the filtration chamber 1b. Water enters the water inlet chamber 1a from the water inlet 2, then enters the filter cartridge 3 for filtration and then enters the filtration chamber 1b, and is discharged from the water outlet 4.

[0018] An adsorption cylinder 5 is rotatably installed inside the filter cartridge 3. The bottom end of the adsorption cylinder 5 is rotatably connected to the filter cartridge 3, and the top end penetrates into the cleaning chamber 1c and is communicated with the cleaning chamber 1c. A cleaning drain port 10 is opened on the cleaning chamber 1c. A reduction motor 11 for connecting and driving the adsorption cylinder 5 to rotate is provided on the filter housing 1. The adsorption cylinder 5 is used to collect the impurities adsorbed from the filter cartridge 3 and converge them into the cleaning chamber 1c and discharge them from the cleaning drain port 10.

[0019] In this embodiment, five negative pressure suction nozzles 6 are installed outside the adsorption cylinder 5. The five negative pressure suction nozzles 6 are arranged at intervals along the length direction of the adsorption cylinder 5, and the angle between adjacent two negative pressure suction nozzles 6 is 90 degrees. Specifically, the orientations of the five negative pressure suction nozzles 6 from left to right are up, front, down, back, and up in sequence. A cleaning brush 7 is provided at the adsorption port end of each negative pressure suction nozzle 6. The cleaning brush 7 wraps the adsorption port end of the negative pressure suction nozzle 6 and contacts the inner wall of the filter cartridge 3.

[0020] Each negative pressure suction nozzle 6 is slidably installed on the adsorption cylinder 5 through a sliding sealing plate 8, as Figure 2 shown. The sliding sealing plate 8 includes an outer fitting section 8a that fits against the outer wall of the adsorption cylinder 5 and an inner sliding section 8b that is slidably embedded in the adsorption cylinder 5 and connected to the outer fitting section 8a. A first water inlet channel 12 communicated with the negative pressure suction nozzle 6 is opened on the sliding sealing plate 8. Five sealing sliding sleeves 9 corresponding to each sliding sealing plate 8 are provided inside the adsorption cylinder 5. Each sealing sliding sleeve 9 includes a sealing sleeve 9a slidably embedded in the adsorption cylinder 5 and a transmission sleeve 9b connected to the inner side of the sealing sleeve 9a. The outer side of the sealing sleeve 9a is connected to the inner sliding section 8b of the sliding sealing plate 8. A second water inlet channel 13 communicated with the first water inlet channel 12 is opened on the sealing sliding sleeve 9. The second water inlet channel 13 is communicated with the inside of the adsorption cylinder 5. The impurities adsorbed by the negative pressure suction nozzle 6 can pass through the first water inlet channel 12 and the second water inlet channel 13 and enter the inside of the adsorption cylinder 5.

[0021] In this embodiment, a transmission block 15 is installed inside the inner side of each transmission sleeve 9b. The transmission blocks 15 are connected to a transmission rod 16. An expansion cylinder 14 is embedded and installed inside the top end of the adsorption cylinder 5. The transmission rod 16 is connected to the output end of the expansion cylinder 14 and can drive the five sealing sliding sleeves 9 to slide synchronously.

[0022] When the filter of the present utility model is self-cleaned, the reduction motor 11 drives the adsorption cylinder 5 to rotate, driving the five negative pressure suction nozzles 6 to rotate. At the same time, the telescopic cylinder 14 drives the transmission rod 16 to move, driving the five sealing sliding sleeves 9 to slide synchronously, and then driving the five negative pressure suction nozzles 6 to slide back and forth through the sliding sealing plate 8, so that the negative pressure suction nozzles 6 can make reciprocating movements while rotating, cooperating with the cleaning brush 7 to comprehensively and specifically adsorb and clean the impurities on the inner wall of the filter cylinder 3. The adsorption area has a wide coverage. After the adsorbed impurities enter the interior of the adsorption cylinder 5, they converge into the cleaning cavity 1c and are discharged together from the cleaning discharge port 10.
